A group of 45 people attend a ball game. There were twice as many children as adults in the group. Set up a system of equations that represent the number of children and adults that attended the game and solve and solve the system to find the number of children who were in the group ADD ANSWER

90

Step-by-step explanation:

Because you have to do 45 x 2 which equals 90

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
